An end effector jaw for an endoscopic surgical instrument includes a tang portion (140, 240), a hollow body portion (121, 220), and a hollow nose portion (229). The hollow body portion (121, 220) has a lateral side (121, 221) and a proximal portion (127, 227) connecting the lateral side (121, 221) to the tang portion (140, 240). The hollow nose portion (229) is connected to the lateral side (121, 227) and has a grasping surface (225) and at least one grasping tooth (1231, 2252) extending from the grasping surface (225) and having a backward curve shape, the hollow body portion (121, 220) and the hollow nose portion (229) defining at least part of a biopsy cup for receiving a tissue sample therein, the at least one grasping (1231, 2252) forming a grasping element for grasping the tissue sample.
